COMBINATION LOCK.

" Application filed November 20, 1924. Serial No. 751,157.

1 '0 all whom it may concern:

Be it known that I, LOUIS V. ARoNsoN, citizen of the United States, residing at Newark, in, the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Combination Locks, of which the following is a specification. 3

The invention relates to combination locks and has as its object the provision of a lock of great simplicity, and which may be manufactured cheaply so as to make possible its use with a toy. g

A further object of the invention is the provision of an exceedingly simple combination lock which shall function accurately.

A further object of the invention is the provision of a combination lock which may be made substantially throughout of metal stampings.

A further object of the invention is the provision of a combination lock wherein the permutation elements are mounted bolt to slide therewith. v

Further objects of the invention'will appear from the following description when read in connection with'the accompanying drawings, wherein Fig. 1 is a front elevation;

Fig. 2 is a central vertical section on line 22 of Fig. 1;

Fig. 3 is a vertical section on line 3-3 of Fig. 2; and

Fig. 1 is a rear elevation with the lock cover removed.

As shown, the look is applied to a receptacle having an outer wall 10 and a circular end wall 11, in which a door 12, carrying the lock embodying the invention, is hinged upon a pintle 13;

As shown, the lock comprises a dial 14 carrying a flat knob 15 integral therewith, and rigidly secured to a pin 16 passing through the door, through the bolt 17, and having mounted thereon the permutation elements 1819.

The element 18 is rigidly secured to the pin 16, and the element 19 is loosely mounted thereon.

Annular rings 2021 are shown rigidly secured to the permutation element 19 and freely movable on the pin 16. To cause the picking up of the permutation element 19, when the permutation element 18 is revolved by the preparatory movement of the upon the dial 15, a notch 22 is provided in the ring 20, to co-act with a'pawl 23 mounted upon a pin 24, carr1ed'by the permutation member 18. To press the pawl toward tl'ie'ring;

20, a spring 25 is shown mounted upon a pin 26also carriedby the permutation member 18.

The bolt 17, carrying the pin 16, the dial, and the permutation elements, is adapted to slide on the door 12 so that the end 27 ofthe'bolt escapes from its position in the rear of the wall 11 about the door opening. To

permit of the sliding movement of the lock,

the opening through which the pin 16 extends, is formed as a slot 28.

To prevent unauthorized movement of the bolt, a fence 29 is shown standing opposite the edges of the permutation elements l819.

'To permit the authorized movement of the bolt, a gate is shown in each of the permutation elements at 3031. When the two gates are brought in registry at the same time with the fence 29, the bolt may bereright, in the embodiment shown, the pawl- 23 coming into contact with the notch 22 to bring the gates into a predetermined relative position, and, by continued movement in the preparatory direction, to a position in which the correct number registers with the zero mark 32 on the door, the gate 30, in the permutation element 19 being brought opposite the fence 29.

By reversal of the movement of the dial, the permutation element 19 will remain in place and the gate of the element 18 will be brought into registry with the gate 30 and to a position opposite the fence 29. If now the dial be moved bodily upon the door, the bolt will be retracted and the door permitted to open.

To hold the permutation element 19 from being moved by friction between the same and the permutation element 18, durin the second setting of the dial, a spring 33, 12A" ing two portions 3 35, which press against the edge of the permutation element 19, is provided. The spring is shown as formed from a metal stamping, and the central por-' tion has a flange 36 bent at an angle to the body of the spring and mounted upon the bolt 17 asby means of a rivet. 37. I

A cover 37 is shown for the mechanism of the lock and may be secured to the door by tabs 3839 passed through openings in the body of the door and clinched.

A retaining member is also shown, through which the bolt projects to take the strain of unauthorized attempts to open the door. The member 40 is shown as provided with projecting portions passing through the door and headed as at 41.

It will be seen that substantially the entire lock maybe made up of metal stampings, and the assembly being very simple, the lock will be exceedingly cheap to produce as well as eliicient in operation.

Minor changes may be made in the physical embodiment of the invention without departing from the spirit.
